10 Best Fisher Metal Detectors 2025 in the United States

The Fisher Labs XLT30D Liquid Leak Detector is designed primarily for detecting leaks rather than traditional metal detection. This product features a battery-powered operation, making it easy to use in various locations without worrying about power supply. Although it is lightweight at just 0.01 ounces, which enhances portability, the ergonomic design might not be as refined for extended usage periods.

When it comes to the essential specs for metal detection, this model’s operating frequency is tailored for leak detection, so those seeking traditional metal detecting functionalities might find it lacking. The Big Foot and Multi-Sensor features can be beneficial for specific tasks, yet they might not align perfectly with the requirements of traditional metal detector users.

For those looking for a reliable leak detection tool in industrial applications, this product could be an excellent fit. However, enthusiasts or professionals seeking a comprehensive metal detector might need to explore more specialized options that offer robust features such as discrimination, ground balance, and detailed depth indicators. While the Fisher Labs XLT30D can be handy for its intended purpose, it may not meet the expectations of users focused on traditional metal detection.

The Fisher Labs M9711 Metal Detector is designed primarily for locating valves and metal boxes, making it a practical choice for utility workers and hobbyists. One of its standout features is the automatic retune button, which helps maintain optimal sensitivity during use, coupled with a sensitivity selector for fine-tuning detection. With an operating frequency of 4.5kHz, it can effectively detect larger metallic objects, though it may struggle with smaller targets compared to detectors operating at higher frequencies.

The manual ground compensation feature is a plus for users who may encounter varying soil conditions, allowing for better performance in different environments. The 11” search coil provides a decent range, enabling efficient searching over larger areas. An added headphone jack is convenient for private listening, which is great in crowded or noisy locations.

In terms of ergonomics, the M9711 weighs 3.9lbs, which is relatively manageable for extended use, although some users might find it slightly cumbersome over long periods. The adjustable length from 38” to 50” caters well to users of different heights, making it more comfortable for a wider range of people. It has a few drawbacks. The reliance on 2 x 9V batteries may not be the most convenient option for all users, especially considering the battery life of 25 to 35 hours, which may necessitate regular replacements during longer outings. Additionally, while the 4.5kHz frequency is good for certain applications, it may not be versatile enough for users looking to detect a variety of small objects or coins.

The Fisher Labs M9711 is a reliable metal detector for specific tasks like locating valves and boxes, making it suitable for professionals in utilities. For hobbyists or treasure hunters seeking a more versatile device, considering a model with a higher frequency and longer battery life might be beneficial.

The Fisher Gold Bug 2 Metal Detector is designed specifically for precise gold nugget detection in mineralized soils. One of its standout features is its ultra-high operating frequency of 71 kHz, which provides exceptional sensitivity for finding small and deep gold nuggets. This makes it an excellent choice for both professional and amateur prospectors working in challenging environments.

The 10.5-inch waterproof elliptical search coil enhances ground coverage and depth, while its ESI shielding minimizes interference, ensuring stable and accurate detection even in difficult terrains. The advanced ground balance control and mineralization adjustments enable users to fine-tune the detector's performance for various soil conditions, including areas with black sand and hot rocks, improving its effectiveness in extreme environments. Additionally, the iron discrimination mode and audio boost feature help filter out unwanted targets and amplify faint signals, making detection more precise and efficient.

Weighing only 2.9 lbs., the Gold Bug 2 is lightweight and ergonomically designed for prolonged use, with features like a hip-mountable control housing, cushioned armrest, and foam grip handle for added comfort. Its robust construction, including a dust and moisture-resistant control housing, ensures durability in outdoor conditions. Powered by two 9-volt batteries, it offers up to 35 hours of operation, allowing for extended detecting sessions. However, some users might find the manual ground balance and mineralization adjustments challenging if they are not familiar with these settings. Additionally, the relatively high frequency may not be as effective for detecting larger or deeper targets that are not gold.
